It's a huge understatement to say that being president is a very demanding job. It requires some serious time management and work coping skills. 99U has compiled a list of things President Obama does that keep him going and focused and help him get things done.

Obama gets a head start on his day the night before. He stays up until 1am (long after his family has turned in), leafing through the binders of documents he has to review and getting his thoughts organized for the next day.

He protects his personal time. That late night period is his personal time, "the closest thing he experiences to privacy," writes Lewis. Two other blocks of time he keeps sacred are his morning workout and dinner with his daughters.

He limits decision fatigue with strict routines. Obama only wears blue or gray suits; he can't afford to have to make small decisions like what he eats or wears because he has too many other decisions to make. Similarly, according to Lizza's New Yorker article, the president prefers "decision" memos with three checkboxes at the bottom for agree, disagree, or discuss.

Whatever your political leanings, we can all learn a lot from the way President Obama juggles his work and days. Check out the 99U post for more tips and the excellent Vanity Fair and New Yorker articles for more detailed portraits (I especially like Lewis's account of playing basketball with the president).
